A simple frittata gets big flavour thanks to merguez sausage. Add almost any veg you have to hand - great options are sliced red pepper, shredded courgette, spinach or a mixture.
I don't find cheese necessary in this frittata thanks to all the flavour from the merguez, but you could opt to add about 50 to 75g crumbled feta cheese or a milder soft goat's cheese. For even more spice, whisk a bit of harissa into the beaten eggs!
